Abstract
Abstract A high density infrared detector array is stacked with and bonded to a coementing silicon microcircuit chip by interconnecting solder bumps. The silicon chip is provided with a plurality of window areas, each of said areas positioned in registration with a corresponding underlying detector element for permitting the transmission of infrared radiation to the array.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
126 words
A device for processing infrared radiation information, comprising, in combination: an array of infrared detector elements, each of said elements producing an output signal at a solderable terminal formed thereon; and a chip stacked upon said array and having a multiplicity of circuits formed thereon, each of said circuits having a solderable terminal formed thereon in registration with corresponding ones of said element terminals for electrically and mechanically bonding thereto and for receiving the respective output signals therefrom, said circuits being distributed suitably for the formation of a plurality of window areas, each of said window areas being transparent to infrared radiation and formed in registration with corresponding ones of said detector elements for permitting the transmission of the radiation through said chip to said array.
Claim 2
Independent Claim
126 words
A device for processing infrared radiation information, comprising, in combination: an array of infrared detector elements, each of said elements producing an output signal at a solderable terminal formed thereon; and a chip stacked upon said array and having a multiplicity of circuits formed thereon, each of said circuits having a solderable terminal formed thereon in registration with corresponding ones of said element terminals for electrically and mechanically bonding thereto and for receiving the respective output signals therefrom, said circuits being distributed suitably for the formation of a plurality of window areas, each of said window areas being transparent to infrared radiation and formed in registration with corresponding ones of said detector elements for permitting the transmission of the radiation through said chip to said array.
